[GitHub] [incubator-pinot] fx19880617 opened a new issue #5565: Timeout exceptions is not set clearly in query response.

fx19880617 opened a new issue #5565:
URL: https://github.com/apache/incubator-pinot/issues/5565


   Currently we don't see timeout exception in pinot query exceptions.
   Sometimes we just see pure empty response, and sometime we see the message below, which shows no clue of this is timeout and users need to see Pinot server log to identify the real issue is timeout.
   
   This also prevents client side to retry on certain exceptions.
